While we love a lively debate about the latest in dietary science or the hot new workout craze, the truth is that great health isn’t so complicated. It all comes down to a few simple rules. Besides exercising, eating fruits and veggies and never smoking (you already knew that, right?), here’s what the healthiest women do every day.RELATED: 21 Reasons You’ll Live Longer Than Your FriendsThey put themselves first”Many women don’t approach their own needs thoughtfully,” says David Katz, MD, president of the American College of Lifestyle Medicine and author of Disease Proof. “They just give themselves whatever is left over”—like eating scraps off your kid’s plate rather than making your own dinner, or sacrificing sleep to squeeze in an extra work report. But time for yourself should be the last thing to come off your schedule.They’re not afraid of fatWe now know that the type of fat you consume is more important than the amount. For one, low-fat diets don’t seem to be any more effective than higher-fat diets at helping people lose weight. And when it comes to heart health, replacing saturated fats with refined carbs doesn’t do you any favors—but replacing them with unsaturated fats can reduce heart disease risk by up to 25 percent, says a recent study from the Harvard T.H. Chan School of Public Health. Aim to get most of your fat from foods rich in mono- and polyunsaturated fats (such as avocados, nuts, seeds and fatty fish), says Marjorie Nolan Cohn, RDN, spokesperson for the Academy of Nutrition and Dietetics.RELATED: Best Superfoods for Weight LossThey don’t drink their caloriesOther than water, the only drinks worth a pour are coffee (mind the cream and sugar) and tea, along with the occasional alcoholic drink (no more than one per day), if you so desire. Even juices should be seen as a treat. That’s because juicing removes most of the fruit’s healthy fiber while preserving the sugar.They use a shot of sunscreenAs in 1 ounce, enough to fill a shot glass, spread out over every exposed inch of the body. Don’t forget places like your ears (the third most common spot for basal cell carcinoma, a type of skin cancer), neck, the back of your hands and—during sandal season—your toes, plus SPF lip balm.RELATED: 22 Strange Ways the Sun May Affect Your BodyThey don’t fight stress with screensBy the end of a long, harried day, the path of least resistance is often paved with wine, Häagen-Dazs and endless mind-dulling games of Candy Crush. But these types of activities offer only instant gratification—a little hit of dopamine in the brain’s reward center. “Do something instead that fosters a genuine positive emotion; that’s what induces feelings of calm and safety and puts the brakes on your body’s stress response,” says sociologist Christine Carter, PhD, senior fellow at UC Berkeley’s Greater Good Science Center and author of The Sweet Spot. One of the best ways to tap into good vibes: Connect with others in person, not just via Instagram and Facebook likes…

I’m guilty: I snooped around Jillian Michaels’ dressing room. I was left alone for a few minutes while she filmed part of her new show, Sweat Inc., and I spied something far too tempting to ignore: her stash of snacks.After all, the fitness entrepreneur, 41, is a powerhouse, and I wanted to know what fuel she’s putting in her machine. Her snacks include organic brown rice crackers; dry roasted, salted almonds; and root vegetable chips.And, boy, does Jillian need to keep her energy up. In addition to this show, which debuts on Spike TV this month, she’s shooting an E! channel docuseries, Just Jillian, that captures her life at work and at home with her partner, Heidi Rhoades, and their two kids, Lukensia, 5, and Phoenix, 3, set to air in January. She’s also busy writing a new book for mothers-to-be, Hot Mom, Healthy Baby, and has just launched a fresh-food line called Slim Soul (in select supermarkets). And that’s on top of the Impact fitness wear she created for Kmart. Jillian is still in full exercise garb because she’s just finished a workout on camera—but despite the name of her show, she isn’t breaking a sweat. “I take better care of my body now than I did at 20,” Jillian says as we walk across set to grab lunch. “I got kids. I’m like, ‘I need to be around for a while!'”RELATED: Where to Buy the Cool Clothes Jillian Michaels Is Wearing in Our October IssueBack in her dressing room, she sits cross-legged on the floor. Diving into salad and ravioli, Jillian shatters some myths about working out and offers seriously practical advice on leaning in to get the body and life we deserve.I notice you’re not eating any of the grilled chicken.I don’t eat a ton of meat. I have grass-fed beef once a week, and farmed shrimp and ocean-caught salmon, and sometimes some sole or tuna. I’m looking at the planet and really starting to see how our food policy and food practices are destroying the world. Even grass-fed beef is so bad for the planet. And we’re fishing out the oceans.Do you cook at home?We’re terrible cooks! Well, Heidi is a good cook, but she doesn’t have a ton of time. I am a terrible chef, so I hate to admit this, but one of the things we do is have a couple of restaurants that feed us—literally. The more I work out, the more carbs I need. I stopped eating sugar in December. Carbs, yes, but straight sugar, no.Is there one food rule you think we should all follow?I don’t believe in all or nothing. I think the key contents are: Don’t overeat, avoid chemicals as often as possible and…that’s it.RELATED: Transform Your Body in 4 Weeks With Jillian’s 7-Move Circuit WorkoutAnd of course people always want to know what one move is best for the whole body. Is there one move?People think there is a simple solution. Honestly, the majority of people with fitness phenomenons build a business by giving you a magic-bullet answer: “Eat whatever you want, except this, and you’ll lose weight.” “Eat whatever you want, but only during these hours.” “Just do one exercise…

My face is so flaky. What should I do?Blowing your nose a hundred times. Battling arctic winds. Winter conditions can irritate your skin big time and cause flakiness. “We call it ‘irritant contact dermatitis,’ and anything that aggravates skin can bring it on,” says Mona Gohara, MD, associate clinical professor of dermatology at the Yale School of Medicine. The obvious—but key—solution is to moisturize: Use a rich cream that contains a humectant like glycerin or hyaluronic acid. For scaly patches, try a balm with emollient shea butter or argan oil, like Cosmedix Rescue + Intense Hydrating Balm & Mask ($59; amazon.com).RELATED: 8 Steps to Healthy Skin at Every AgeWhat’s with the bright red blotches on my face and neck?Those spots are a sign that you’re sensitive to cold. You could have rosacea—a flushing skin condition—but the capillaries in your skin may just dilate when exposed to triggers like dry heat or temperatures. Try taking cooler showers and using fragrance-free products, says Dr. Gohara. Thermal mists that contain the inflammation-busting mineral selenium can help when used on affected areas, as can a cold compress on the back of your neck.What are those tiny red lines around my nose?The technical term: telangiectasias. But we know them as dilated capillaries (some people say they’re “broken” capillaries, but they’re not). Exposure to cold, biting winds makes the vessels under the skin expand and become visible. You may see them on your cheeks and chin, too. The hard truth is that they won’t totally go away without a laser treatment (you’ll need three to six sessions, each $300 and up). The treatment heats the capillaries to permanently close them. To ease inflammation without a trip to the derm, use products with soothing ingredients like chamomile, calendula, and white tea. We like L’Occitane Shea Butter Smoothing Fluid ($49; usa.loccitane.com).RELATED: 20 Habits That Make You Miserable Every WinterI have little red bumps on my upper arms that get worse in winter. Help!The delightful chicken skin! Those raised spots develop when dead cells build up within the hair follicles, forming hard little plugs, explains Dr. Gohara. You can’t get rid of them, but you can improve their appearance: Start with soap-free wash in the shower, then apply a body lotion with alpha hydroxy acids to gently smooth the skin’s texture. Our pick: AmLactin Moisturizing Body Lotion ($21; amazon.com).

What are those tiny white dots under my eyes?Those little lumps are not acne (so stop trying to squeeze them!). In fact, they’re likely miniature cysts, called milia, which are often caused by heavy creams or other occlusive products used under the eyes, says Doris Day, MD, a dermatologist in New York City. Solution: Dab a gentle chemical exfoliator over the area (avoiding eyes); it will help shed skin, which may coax out the cysts…
